ROTARY BRUSH.

SPECIFICATION forming part of Letters Patent No. 533,833, dated February5, 1895. Application filed April 27,1894. Serial No, 509,220. (Nomodel.)

.To aZZ whom it may concern.-

Be it known that I, HAROLD A. Wnssrnn, of Haverhill, in the county ofEssex and State of Massachusetts, have invented certain new and usefulImprovements in Rotary Brushes, of which the following is aspecification.

This invention has for its object to provide a rotary brush adapted forcleaning and polishing parts of boots and shoes, and other articles, andit consists in a brush comprising the construction substantially ashereinafter described and claimed.

Of the accompanying drawings, forming part of this specification,-Figure1 represents a perspective view of the hub, a portion of the ligature,and some of the strips, showin g the manner of making the improvedbrush. Fig. 2 represents a side view of the brush, one of the end platesor collars being removed. Fig. 3 represents a section on line 33 of Fig.2.

Ihe same letters of reference indicate the same parts in all thefigures.

In carrying out my invention I take a cylindrical core or hub a, whichis preferably of wood, and attach to the periphery thereof one end of aflexible cord or ligature b, using any suitable fastening device, suchas a tack b driven into the hub and engaged with the ligature. I thenfold or bend over the ligature a series of strips or pieces 0 of textilefabric, preferably thin woolen cloth, the central part of each stripbearing on the ligature. I arrange the strips edge to edge upon theligature, and wind the latter helically upon the hub, thus securing thestrips to the hub and causing them to stand out radially therefrom,large numbers of the strips being brought side by side by the windingoperation, so that they collectively form a dense mass of radiatingstrips, the outer ends of which are exposed and constitute a soft,yielding brushing surface.

When the winding operation is completed,

the other end of the ligature is permanently secured to the huh. Iprefer to secure the convolutions to the hub by glue or cement appliedto the ligature and to the portions of the strip in contact therewith asthe winding progresses, thus preventing any possibility of theseparation of the strips from the hub.

In applying the strips to the ligature, I.

crowd or pucker the portions lying on the ligature, to reduce the widthof the strips at their inner portions. This puckering or crimping of thestrips at their doubled inner portions, not only permits perfectlyrectangular pieces to be used, but also renders the portions of thecompleted brush that are near the hub so dense that when an article tobe polished is pressed hard against the brush, there can be no contactof said article with the hub or the side flanges usually employed. Therectangular pieces or flaps can readily be out so that there will be nowaste of ma terial. In the completed brush, the flaps will collectivelyform a practically continuous brushing surface the edges of which arenot liable to fray out at one point more than another, owing to the factthat each piece is originally rectangular so that its edges which formthe brushing surfaces are parallel with the threads running in-onedirection.

I claim- 1. A rotary brush composed of a rigid core or hub, a flexibleligature secured to said hub and helically wound thereon, and a seriesof rectangular strips of textile fabric bent around said ligature andplaced edge to edge thereon and crimped or puckered at their innerportions, said strips being held by the ligature in a helical seriesradiating from the hub and collectively forming a brush the free ends ofthe strips constituting the exposed surface of the brush, as set forth.

2. A rotary brush composed of a rigid core or hub, a flexible ligaturesecured to said hub and helically wound thereon, and a series ofrectangular strips of textile fabric bent around said ligature andplaced edge to edge thereon and crimped or puckered at their innorportions, the ligature and strips being glued or cemented to the hub, asset forth.

In testimony whereof I have signed my name to this specification, in thepresence of two subscribing witnesses, this 21st day of April, A. D.1894.
